One of the greatest challenges of working in the underwater regime is the severe limitations of acoustic communications. This problem becomes even more evident in multi-vehicle autonomy, when vehicles must continually update each other with their state and intentions to achieve cooperative goals. In order to support tests of a multi-vehicle arbiter framework, an optimization scheme was created and implemented as a MOOS module to enable sufficient message passing between vehicles. Using this tool, vehicle state and destination, shared map updates, updated algorithm parameters, target information, and decision reconciliation can be effectively shared between vehicles using the published Compact Control Language (CCL) standard for acoustic messages.

!! Talk-18: ''The EvoLogics Acoustic Modem Integration into NURC’s MOOS Environment''
!!!!%color=#449944% '''Arjan Vermeij, NATO Undersea Research Centre'''
The NATO Undersea Research Centre(NURC) recently acquired acoustic modems from EvoLogics. These modems, of type S2C R 8/16, are to be used in an upcoming sea trial on board our two Ocean Explorer (OEX) autonomous underwater vehicles (AUVs). They should provide the ability to communicate at longer ranges and possibly with a higher data throughput, than currently achievable with our WHOI (Woods Hole Oceanographic Institute) Micro-Modems.
As part of the Collaborative Anti-Submarine Warfare programme, NURC researches communications and networks in the maritime environment. This project aims to evolve underwater communications from point-to-point underwater messaging into true net- working, taking into account the limitations imposed by the underwater acoustic channel, such as high latency and bandwidth constraints. This involves the development of an underwater communications stack.
There are some requirements on the integration of the EvoLogics modem into NURC’s MOOS environment:
* The EvoLogics modem has the ability to operate in different modes, which should remain available.
* The MAC layer, already available inthe EvoLogics modem, should be usable.
* The integration should allow for potential replacement and addition of components developed within the communications and networking task.
* If possible, the EvoLogics modem should be able to work in parallel to the WHOI Micro-Modem.
This presentation discusses the design and developed applications as partof this inte- gration process. Furthermore, initial results obtained during the June engineering trial are presented.
A reprint of this presentation, including the source code of the developed processes, will be made available through NURC, after the conference.

!!!!%color=#449944% '''Henrik Schmidt, Toby Schneider, MIT Laboratory for Autonomous Marine Sensing Systems (LAMSS), Center for Ocean Engineering'''
The use of autonomous underwater vehicles as platform for passive and active acoustic sensing provides the possibility of adaptively changing the heading, speed and depth for optimal sensing performance. For example, by measuring the local ambient noise directivity, the autonomy can choose a heading which minimizes the interference with the source of interest, or the vehicle can use its measured sound speed profile to choose an optimal depth for sensing or communication with other assets. The latter type of environmental adaptation requires that robust features of the acoustic environment are identified and modeled. In shallow water this is possible to a very limited degree, e.g. selecting a depth which is on the same side of the thermocline, whereas other features focusing the acoustic energy are in general unreliable due to fluctuations in the acoustic environment. In deep water, on the other hand, the deep pressure gradient of the sound speed is extremely stable and may be robustly exploited. Thus, a platform operating near the bottom in the deep ocean will have a direct acoustic path to and from a shallow receiver or source within the so-called RAP cone (Reliable Acoustic Path), extending to ranges of approximately 30 km. However, by moving up in the water column, the upward refractive sound speed profile will extend the direct path up to 60 km range. This so-called convergence zone path is extremely stable and predictable, and an optimal depth for acoustically connecting with a shallow source or receiver can be modeled very robustly. An IvP-Helm behavior has been developed that uses as an objective function the depth-dependent transmission loss or SNR, modeled onboard the vehicle. The behavior has not yet been field tested, but the performance will be demonstrated using the MIT-LAMSS simulation environment [Work supported by DARPA].

!!!!%color=#449944% '''Kevin LePage, NATO Undersea Research Centre'''
The NATO Undersea Research Centre is currently exploring system concepts for collaborative ASW using AUVs. As part of this effort the design of autonomy algorithms (behaviours) which are adaptive on Doppler-sensitive sonar signals is being pursued. MOOS-IvP is currently used onboard two Ocean Explorer AUVs which each have horizontal line arrays and accompanying CW signal processing software capable of converting acoustic signals into time-bearing-Doppler contacts. These contacts are fused with FM contacts within NURC's DMHT tracker. The fused CW-FM tracks are acted on by the behaviours implemented within the MOOS-IvP software architecture. In this talk we explore the performance of a behaviour which seeks to maximize the future Doppler on contacts of interest. The collaborative use of this behaviour with a second vehicle performing traditional FM processing is also considered.

!!!!%color=#449944% '''Matthew J. Bays, Jean-François Kamath and Signe A. Redfield, NSWC-PCD'''
We address the integration and field testing of a novel reacquire/identify(RID) pattern generation algorithm. This algorithm, known as Probabilistic Reacquire/ID Optimal Path Selection (PROPS), is designed to plan a path for a sidescan sonar equipped underwater vehicle in order to produce multiple views of a cluster of discrete targets. The desired pattern minimizes the total number of turns and time required, while attaining appropriate coverage of the targets. Initial tests of the pattern generation algorithm suggest that it requires between 35% and 95% of the time required by the standard “star” RID pattern. Following a brief description of the algorithm itself, we present the integration of the algorithm, both as a stand-alone MOOS module and as a library using a standard RID pattern generator created from the MOOS-IvP Helm autonomy toolkit. Simulation and field test results of the algorithm on a REMUS 100 autonomous underwater vehicle are included.

!! ''MOOS-Enabled Semi-Autonomous Remote USV Operations''
%color=#449944% '''Signe Redfield, NSWC-PCD'''
A multi-vehicle mission involving simultaneous identification (by UUVs) and neutralization (by a USV) of targets is complicated by the need to keep the neutralization efforts distant from the
identification vehicles. As targets are identified by the UUVs, they are relayed to the USV for imaging (proxy for neutralization). The USV plansa sequence of neutralization efforts based on desired efficiency (prosecuting targets in close proximity in the same sequence), neutralization capacity (number of targets that can be prosecuted without reloading), the location of the reloading depot, and distance from other vehicles. We present a solution to this variation of the capacitated vehicle routing problem, implemented on a semi-autonomous USV. MOOS performed the autonomous portion of the mission running on a remote laptop while a human operator ran a teleoperated underwater vehicle launched and retrieved from the USV as a proxy for the neutralization system as each target was reached. Together the system demonstrated semi-autonomous remote USV operations, with the human operator working smoothly with the autonomous system.

The USV plans a sequence of neutralization efforts based on desired efficiency (prosecuting targets in close proximity in the same sequence), neutralization capacity (number of targets that can be prosecuted without reloading), the location of the reloading depot, and distance from other vehicles. We present a solution to this variation of the capacitated vehicle routing problem, implemented on a semi-autonomous USV. MOOS performed the autonomous portion of the mission running on a remote laptop while a human operator ran a teleoperated underwater vehicle launched and retrieved from the USV as a proxy for the neutralization system as each target was reached. Together the system demonstrated semi-autonomous remote USV operations, with the human operator working smoothly with the autonomous system.

This talk addresses the challenge of autonomously and adaptively tracking features of the underwater environment using AUVs running the MOOS-IvP autonomy software. This problem is addressed from concept to implementation in the field on various AUV platforms, developing specifically the example of thermocline tracking. Some recent research involving methods for feature tracking on board multiple AUVs operating simultaneously and collaboratively to detect an underwater feature will also be discussed briefly.

One of the greatest challenges of working in the underwater regime is the severe limitations of acoustic communications. This problem becomes even more evident in multi-vehicle autonomy, when vehicles must continually update each other with their state and intentions to achieve cooperative goals. In order to support tests of a multi-vehicle arbiter framework, an optimization scheme was created and implemented as a MOOS module to enable sufficient message passing between vehicles. Using this tool, vehicle state and destination, shared map updates, updated algorithm parameters, target information, and decision reconciliation can be effectively shared between vehicles using the published Compact Control Language (CCL) standard for acoustic messages.
